Accupro 14796226 Corner Radius End Mill 0.0312in 3 Flute

Product Description

The ACCUPRO 14796226 is a miniature solid carbide corner radius end mill designed for precision milling operations requiring tight tolerances and fine detail work. With a 0.0312-inch cutting diameter and a 0.005-inch corner radius, this tool produces controlled edge geometry on small features. The 3-flute, right-hand spiral configuration with a 30-degree helix angle supports efficient chip evacuation in confined cut zones. AlTiN coating extends tool life in harder materials by improving heat resistance and surface hardness at the cutting edge. This end mill is center-cutting and suited for plunge entry as well as profiling passes in CNC machining centers.

This miniature end mill is intended for small-part machining in aerospace, medical device, mold and die, and precision instrument manufacturing environments. Its 0.046-inch length of cut and 0.25-inch reach length make it appropriate for shallow pockets, fine contours, and detail passes where a standard end mill would not fit. A 1/8-inch shank diameter allows it to seat in standard collets and tool holders sized for miniature tooling. It is typically run by machinists and CNC programmers on vertical machining centers, CNC routers, and high-speed spindle setups.

Key Features

• 0.005-inch corner radius reduces stress concentration and improves edge durability on finished surfaces
• Solid micrograin carbide construction supports high rigidity in small-diameter tools
• AlTiN coating improves wear resistance and heat tolerance in harder workpiece materials
• 30-degree helix spiral flutes promote chip flow in tight clearance environments
• Center-cutting design allows direct plunge entry without pre-drilling
• Extended reach construction with 0.25-inch reach length accommodates deeper feature access

Compatibility

Designed for use with standard 1/8-inch collets and tool holders compatible with miniature series end mills. Suitable for machining a range of materials including hardened steels, stainless steel, titanium, and other alloys where AlTiN coating provides thermal and wear advantages.

Installation Notes

Installation should be performed by a qualified machinist or CNC programmer. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the 1/8-inch shank fully into the collet and torque the tool holder to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a production run, as miniature tooling is sensitive to even small amounts of spindle or collet runout.
